Where is the throttle body on an SC?

[86 911]

Sorry for the easy question, but where would the throttle body be located on a 3.0 litre SC engine? I was in auto shop class this morning and I got a chance to work on my 911 and the shop teacher suggested a BG product that cleaned the throttle body. Other than that, I got a chance to add a can of BG Induction System Cleaner to the fuel. This stuff works great! I just couldn't find the throttle body to add that other cleaner to it!

Open the black air box cover, remove the filter and you should be able to look back in there and see it.

Follow the throttle linkage to where it actuates the throttle shaft. The inside of the throttle body is only visible when removing the black, soft bellow/boot on top. (It has 2 large clamps to hold it down)
Just removing the air filter is not really showing the throttle body; it'll show you just the air sensor plate/lever.
Be careful with any additives; Porsche doesn't recommend any.
Just adding injector cleaner into the gas tank now and then is good.
The throttle body needs no cleaning, just get a new airfilter to keep the dirt out. As a novice, don't overfill the engine oil! If you find oil inside the airbox (Under the airfilter) you may have overfilled. Keep the level midway on the stick when hot and running, not more than midway!

LOL. Thanks bb80sc and Gunter. I've read quite a few "I've overfilled my oil tabk posts" so thanks for the reminder. I'll take your advice then and not add any additives to the throttle body. By the way, here is the induction system cleaner I used:


This stuff is great! Maybe Wayne has some here on his site.
